Answer: Option A. -> The revolution of the Moon around the Earth
:
A
The phases of the Moon, also called the Lunar phases, occur due to the Moon's revolution around the Earth. Due to the Moon's different positions around the Earth, we can see different sections of surface of the moon which are illuminated by the Sun, and which reflect the sunlight toward us.
